I was reading an article about the ancient Greek and Roman gods of mythology...
Zeus/Jupiter... Poseidon/Neptune... Athena/Minerva... Apollo/Sol... Aphrodite/Venus...
Dionysus/Bacchus... Ares/Mars... Hermes/Mercury... Hera/Juno... Hades/Pluto...
and it occurred to me that a few of them are shown on casino chips...

I'm sure there are more, but this is all I could come up with on short notice.
